COLOR-HARMONIZER.

SPECIFIGATION forming part of Letters Patent N o. 518,399, dated January 23, 1894.

Application filecl July 28, 1893.

To all whom it maty con/ccm,.-

Be it known that I, EDUARD KREUTZER, drawing-master, of 37 Albrechtstrasse, W'iesbaden, in the German Empire, have invented a new and useful Color-Harmonizer, of which the followingis a specification, reference being had therein to the accompanying drawings, in which- The invention is shown in Figures 1 and 2, in plan, a border being shown in Fig. 1 which is omitted in Fig. 2.

This invention relates to a movable and adj ustable table consisting of two concentric disks divided into Sections of different colors and capable of being moved to any desired position in relation to each other, the object being to enable harmonious sets or combinations of colors to be formed, and colors that match or agree with each other to be found or determined. For this purpose the two disks, such as shown by way of example in the annexed drawings, are divided into twelve eqnal parts or Sections, each of different color, and each disk havingsections colored as follows: three primary colors: yellow, red, blue; three secondary colors: orange, Violet, green; and six colors made up of combined primary and secondary colors: orange-yellow, orangered, Violet-red, Violet-blue, bluish-green, and yellowish-green.

The order of succession of the colors on both disks is the same, viz:-first, yellow; Second, orange; third, cinnabar red; fourth, crimson; fifth, purple; sixth, purple Violet; Seventh' and eighth, ultramarine blue; ninth, Turkish-blue; tenth, bluish green; eleventh, cinnabar green, and twelfth, yellowish green. The colors of the larger of the two disks gradually become lighter in shade toward the circumference, and those of the smaller disk gradually become of a deeper shade as they approach the center. A gray annular border surrounds the twelve colors of the' larger disk, the ontermost portion of which is occupied by the three tertiary colors, viz: yellowish brown, bluish brown, and reddish brown. These diversely colored sections of the disks may be arranged in any imaginable relation to, orjuxtaposition with, each other, so that, whenever anyptwo colors are placed Serial No. 481,715. (No model.)

side by side, the degree of Contrast or harmon y existing between them immediately becomes manifest, and their fitness, or otherwise, to appear in juxtaposition or conjunctio'n with each other may `be tested, while groups of two, three or four well-matched colors, such as are apt to be required in practice, may be readily formed. Thuscontrasts and effects most pleasing to the eye may be produced by the diagram matic arrangement of two, three, or more colors, either in succession, or in any desired, relation to each other. I will endeavor to illustrate this by afew examples which will explain the operation of the improved color-table. I will assume, to begin with that the two disks are so adj usted that each color of the one coincides with or meets the identical color of the other, and that the arrows marked upon them, respectively, point toward each other. In this case it will be seen that the effect of the juxtaposition` of, say, orange and yellow, is not a pleasing one, owing chieiiy to the affinity these two colors have for each other. Again,

the juxtaposition of two colors of the same shade or tone is generally inharmonious and not to be recommended as they will mostly interfere with each other. Nevertheless, a pleasing effect may be produced by placing two kindred colors side by side, one of which is a shade deeper than the other. For this reason eachvof the colors on the color disk presents an entire scale of shades or tones to facilitate the choice of such two similar colors, as will match when they meet, owing to their different shades.

To find two colors calculated to join'tly exercise a pleasing eifect on the observeifis eye, it is only necessary (for example) so to .adjust the two disks that section No. 1 (yellow) of the inner disk meets section No. 7 (bluishviolet) of the outer disk, when all the other pairs of colors broughtin'to juxtaposition on the table will be found to match and muitually to enhance their value; thus, for example, orange will come next to nltramarine blue, crimson next to bluish green, &c. Combinations of such colors as these will,at all times, have an excellent effect, no matter what may be their shade or degree of opaqueness.

IOO

' More harmonious elfects may be produced by coupling any of the three tertiary colors wlth the eight colors facing them on the larger disk, and in each case the six central colors will form the most pleasing contrasts. As to the four colors of the outer disk which are encompassed by the tertary colors, they are too closely akin to these tertiary colors to produce an agreeable efiect.

If it be desired to form aharmonious group of three colors, i. e., to couple two suitable tIs to illustrate the manner in which the` color table may be utilized both for artistic and manufacturing purposes.

The table may be made of sheet metalv or any other material sufficiently strong and rigid to receive the coats' or layers of colors.

What I claim, and desire to secure by Letters Patent of the United States, is-

,1. A color' harmonizer comprising two or more concentric disks of varying diameter revolubly connected togetheneach disk having its face divided into a 'series of Sections of diflerent colors, substantially as described.

2. A color table consisting of two concentric colorcarrying disks adjustable in relation to each other, and the inner of which carries the primary, secondary and mixed colors arranged on it in twelve (12) cqual Sections or divisions, while the outer disk carries other shades of the same twelve colors and in addition to these, three tertiary colors, thereby enabling colors to be matched at will and harmonious effects to be produced,

substantially as described and illustrated in the acoompanying drawings.

In witness whereof I have hereunto set my hand in presence of two witnesses.
